CENTRIFUGAL ORE -SEPARATOR.

SPECIFICATION forming part Of Letters Patent NO. 499,344, dated June 13,1893. Application filedJ'une 20, 1892- Serial No. 437,361- (No model.) i

To all whom it may concern.-

Be it known that I, ORRINB. PECK,a citizen of the United States,residing at Chicago, Illinois, have invented certain new and usefulImprovements in Centrifugal Ore-Separators, of which the following isaspecification.

The object of my invention has particular reference to the constructionof the separating wheel or vessel used in centrifugal ore .separators,and more specifically to the means for imparting a vibratory motion tosuch vessel, as it performs itsiwork; and my invention consists in thefeatures and details of construction hereinafter described and claimed.

In the drawings, Figure 1 represents a central vertical section of myimproved separator. Fig. 2 is a side elevation of the completeapparatus. Fig. 3 is acentral vertical section. Fig. 4 is a sideelevation of the apparatus shown in modified form. Fig. 5 is a sideelevation, showing one half in vertical section, of a modified form ofapparatus; and Fig. 6 is a plan view, taken in the line 6 of Fig. 5,looking in the direction of the arrow.

In making myimprovements in centrifugal ore separators, for separatingthe worthless from the valuable particles of finely divided or powderymaterial, I make a rotatable wheel or vessel, having a separatingportion or surface, A, the whole being mounted on ashaft, A, driven byapulley, A connected by belting to a suitable motive power, or any otherconvenient way. The material to be treated is introduced through a pipeB, and deposited on the separating surface of the vessel. Water isintroduced through spray pipes, B, to spray water upon the materialbeing treated. A trough or curbing, B surrounds the treatment vessel toreceive the material discharged therefrom, which is carried ofi fromtime to time through the pipe 1). Water is also preferably carriedthrough apipe,B and sprayed on the curbing to facilitate the removal ofthe material. As to these matters of construction and operation,however, I will not enter into minute details, as my invention relatesmore particularly to other features of construction.

As illustrated in the drawings, I prefer to make the treatment vessel intwo parts-the outer rim or portion of which afiords a continuousseparating surface, and is preferably flexibly or elastically connectedto the inner or central portion, which may serve as a supporting framework.

In Figs. 1 2, 3 and 4,1'have shown the outer portion or separatingsurface of the vessel,

connected to the centralportion by means of rivets or screws 0. andscrew bolts 0/ provided with elastic cushions or springs a under theheads of the screw bolts. In this way, the separating surface iselastically connected to the central portion or frame work. The screwbolts and cushions or springs afford means through which the tension ordegree of yield ing ability of the separating surface may be adjusted.

In order to impart a vibratory motion to the treatment vessel, I arrangecam surfaces, C, around its bottom or lower edge, as shown particularlyin Figs. 2, 4 and 5. Immediately beneath these cam surfaces I arrange adisk or ring D, adapted. to be rotated independently of the treatmentvessel, by means of a pulley D. The upper edge of this disk or ring isprovided with cam surfaces, E, alternating in direction of cam surfacewith the cam surfaces 0. As the treatment vessel is rotated, the camsurfaces, C, pass over the cam surfaces E, and produce a constantvibration or jarring of the treatment vessel. The ring or disk D may berotated independently of the treatment vessel, and at a differentdesired rate. of speed, or it may be allowed to remain stationary. Ifthe disk or ring D remains stationary, then it is obvious that theamount of vibration in the treatment vessel will be determined by thespeed of its rotation. If, however, the disk or ring be rotated in thedirection of rotation of the treatment vessel, a less amount ofvibration will be produced, depending upon the speed with which the ringor disk D is rotated. If the parts carrying the cam surfaces be rotatedat the'same speed, then of course no vibration or jarringwill beproduced. I am thus able to vary and regulate the amount of jarring orvibration imparted to the treatment vessel or separating surface, ascircumstances may render desirable.

In Figs. 3 and 4 I have shown the ring or disk D supported on rollers I,and rotated by means of gear wheels I driven by a belt, F, from the mainshaft A. The arrangement of these gear wheels, and the application ofthe power to drive them, will be understood from an inspection of Figs.3 and 4, and need not be further described in detail.

In Figs. 5 and 6 I have shown a modification designed to impart quick,sudden motions, accelerations and retardations, to the treatment vessel,in the path of its rotation, as well as the jarring or vibratory motionsabove explained. To effect this, I have connected the separating portionor surface of the treatment vessel to the inner or hub portion, G, bywhich it is rotated, by flexible connectors, H. These connectors areshown in the form of coiled springs, but it is immaterial whether theybe confined to this form, or otherwise made, so as to flexibly connectthe separating portion with the inner or hub portion of the wheel orvessel. I have also shown the cam surfaces C and E as somewhat moreabrupt or inclined in Fig. 5 than in the other figures, but I do notinsist upon this particular form of arrangement of the cam surfaces. Asthe treatment vessel is carried around in its rotation, the cam surfacesC, when they come into contact with the cam surfaces E, somewhat retardthe speed of the separating portion of the vessel. This deflects thesprings or flexible connectors backward and upward until the camsurfaces 0 have reached the top or highest part of the cam surfaces E,when the tension of the springs or flexible connectors instantly assertsitself, and throws or impels the separating portion or surface of thetreatment vessel downward and forward again. In this way I am able toimpart a compound vibration or jarring motion to the separating portionof the treatment vessel, consisting of a vertical jarring or vibrationcaused by the cam surfaces, and successive jar-rings or movementsforward and backward in the path of rotation of the treatment portion orsurface of the vessel, which in other words will be sub- 3' ectin g theseparating surface of the vessel to shocks by retardations andaccelerations in the path of its rotation and at the same time, toshocks or vibrations transverse to the path of its rotation.

From the above description it will be understood that the inner or hubportion of the treatment vessel serves as a supporting frame work forthe separating surface or portion, and affords means for imparting thedesired rotary movement to it, but if desired, other means may beemployed for supporting and rotating the separating surface, and suchother changes or modifications may be made in my apparatus, or in thedetails thereof, as may be desired, so long as they embody the inventionas set forth in the claims.

Such matters of invention as are herein shown and described, and notbroadly claimed, are described and claimed in my application, Serial No.436,734, filed contemporaneously herewith.

What I regard as new, and desire to secure by Letters Patent, is

1. In centrifugal ore separators, the combination of a rotatingsupporting frame work, a continuous separating surface mounted thereonby elastic connectors, and means for imparting shocks or vibrations tosaid separating surface, substantially as described.

2. In centrifugal ore separators, the combination of a supporting framework, a rotatable separating surface mounted thereon, and means forimparting shocks or vibrations to such separating surface byretardations and accelerations in the path of its revolution,substantially as described.

3. In centrifugal ore separators, the combination of asupporting framework, a rotatable separating surface mounted thereon by elasticconnectors and provided with a series of cam surfaces, an independentlyrotatable disk or ring provided with another series of cam surfacesengaging with the first series, and means for effecting the independentrotation of the two, substantially as described.

4. In centrifugal ore separators, the combination of a supporting framework, a rotatable separating surface mounted thereon and connectedthereto by flexible connectors, means for temporarily retarding thespeed of revolution of the separating surface against the tension of theflexible connectors, and means through the flexible connectors forrecovering the speed of revolution temporarily lost, and means forrotating the separating surface, substantially as described.

5. In centrifugal ore separators, the combination of a supporting framework, a rotatable separating surface mounted thereon, and connectedthereto by flexible connectors, means for temporarily retarding thespeed of revolution of the separating surface against the tension of theflexible connectors, means through the flexible connectors forrecovering the speed of revolution temporarily lost, means for impartingvertical shocks or vibrations to the separating surface, and means forrotating the separating surface, substantially as described.
